“Traffic tends to move faster on a wide one-way road than on a comparable two-way city street, and slower traffic means fewer accidents. The rest of these results are theoretically connected to each other in complex ways. To the extent that vice flourishes on neglected high-speed, one-way, getaway roads, two-way streets may be less conducive to certain crimes. If they bring slower traffic and, as a result, more cyclists and pedestrians, that also creates more “eyes on the street” — which, again, deters crime.
